Technical details
Endpoint
GEThttps://likelihoods.io/api/tools/polymarket/moversWhen to prefer
Use this endpoint when you need a ranked, real-time snapshot of which Polymarket prediction markets are experiencing the largest price shifts or momentum changes. Prefer this over the trending-topics endpoint when you specifically want price-change and volatility signals rather than volume-based popularity. Best for trading signals, market surveillance, or alerting on fast-moving events.
Side effects
- Polymarket Gamma API unavailable — upstream data source down
- Empty or stale market list if no significant movers in recent period
- Rate limiting or payment failure for the $0.01 USDC x402 call
- Truncated market data if response payload is large
- Network timeout on the GET request
